Year-round air conditioner with evaporator band and special heater placement

A year-round air conditioner capable of selective supply of cool and warm air, comprising:

• (a) a housing having an air inlet and an air outlet defined therein;
• (b) a water receptacle within the housing for containing water;
• (c) a wet band assembly comprising an endless band of water-absorbent and air-permeable material capable of traveling, the endless band being arranged to be partly immersed in the water receptacle, thereby to be wetted, and to intervene between the air inlet and the air outlet in the housing;
• (d) a fan within the housing for creating airflow from the air inlet to the air outlet through the endless band of the wet band assembly;
• (e) a damper disposed at the air outlet in the housing and dividing the air outlet into a cool air outlet and a warm air outlet, the damper being pivotable about an axis between a first position where the cool air outlet is opened with the warm air outlet being closed and a second position where the warm air outlet is opened with the cool air outlet being closed, the damper extending obliquely across an air passage so as to change the direction of an air flow in the passage;
• and
• (f) a heater mounted on the surface of the damper and arranged to face the cool air when the damper is in the second position, and further arranged to be outside the air flow when the damper is in the first position.
